Welcome to the forum and the S6 can certainly be a GREAT car. There's a LOT of threads on the subject of S6s and I personally really like them...yes they can potentially be maintenance queens, but it appears that getting a good warranty is mandatory at the time of purchase. Since so many items can require a complete engine drop to get access to.
As for performance
mods, well there are very few. Due to the limited run of vehicles the after-market isn't big for these. I've heard of folks putting actual lambo heads on and then there was a fellow seeking at add a supercharger. But at 400+bhp how much more useable perf are you seeking?
Use the search and you'll see a few threads on the subject... good luck
